Rent & eviction protection

Is 1620 Leavenworth St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Annual rent increase cap

Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

1620 Leavenworth Street is a 12-unit, 3-story multi-family residential building constructed in 1917, currently owned by 1620 Leavenworth St LLC. The Nob Hill property has undergone significant safety upgrades in recent years, including a completed fire alarm system upgrade in mid-2023 costing approximately $39,283, and the removal of six pull stations from fire escapes based on updated safety assessments. The building is fully compliant with its soft-story retrofit requirements, having completed necessary work and received certification.

The property has seen substantial unit improvements, particularly during 2019-2020, with several units (2, 3, 4, and 7) receiving comprehensive kitchen and bathroom remodels including new fixtures and electrical work, with individual renovation costs ranging from $10,000 to $28,000. Historical records show recurring attention to fire safety systems, with multiple fire alarm-related complaints between 2007 and 2021, though all were marked as corrected or.with no merit. Recent routine inspections have shown occasional issues requiring attention, such as the most recent general maintenance complaint from March 2024 regarding fire escape ladder maintenance and various compliance affidavit requirements, though these were abated by April 2024. The building's maintenance history includes regular boiler permit renewals, with the most notable violation occurring in 2016 regarding an unpermitted boiler operation, which was promptly addressed. While the building has experienced periodic issues with garbage and debris in the surrounding area (as evidenced by multiple 311 calls throughout 2024), these external matters are typically addressed promptly by city services.

Risk rating

How 1620 Leavenworth St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 1125 buildings in this neighborhood, 1024 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 9.2%
Moderate concern 76.3%
Severe concern 14.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
